Building Event-Driven Microservices with Kafka
Production patterns for event-driven architecture using Kafka, covering schema evolution, exactly-once delivery, and consumer group strategies.
Building Event-Driven Microservices with Kafka
Why Event-Driven?
Synchronous request-response creates tight coupling. When Service A calls Service B, both must be available simultaneously. Event-driven architecture decouples producers from consumers.
Core Patterns
1. Event Notification
Producer publishes a thin event ("OrderCreated", orderId=123). Consumer fetches details when it's ready.
- Pros: Minimal coupling, small payloads
- Cons: Consumer needs access to producer's API
